IDEMOUNTABLE WHEEL AND HUB CONSTRUCTION.

Application led. February 15, 1921.v Serial No. 445,157.

To aZZ 'whom t may concern. w

Be it known that LBENN A. Baron, a citizen of the United States,residing at Ridgefield, in the county of Fairfield and State ofConnecticut, have invented certain new and useful improvements in`Demountable Wheel and Hub Constructions, of which the following is aspecification.

rlihe invention has foran object to effect improvements in theconstruction of motor vehicle wheels, having for its principal objectthe provision of a new and eicient means for mounting a wheel quicklyupon an axle shaft, in such manner that it may also be quickly removed.It is a purpose'in this connection to obviate the need for theapplication of great force with tools to the dismounting of a wheel,thereby obviating the necessity for the use of special wrenches', orvery heavy similar tools. Another aim is to obviate the use of partsseparate from the wheel assembly or the hub base element upon which thewheel is mounted, or the axle shaft, in effecting' the mounting ordismounting of the wheel regularly. rllhis will obviate the liability ofloss of essential parts whenmaking repairs or replacement. 4

A. further important ob `ect of the invention is to enable the readymanufacture o'f a y wheel body in one part, including the run and hub.

A further aim is to effect an improvement in the rim construction,enablingthe quick removal of pneumatic tire shoes therefrom and theirreplacement rapidly-without the use of special tools.

Additional objects, advantages and features of invention will appearfrom the construction, arrangement and combination of parts involved inthe following` description and drawings wherein, I

Fig

assembly has av hub sleeve portion 15, formeel element of an axle whichin the present instance is represented at 11 as a driving axle shaft.rlhe hub base is'formed with an inner large flange 12, having a seriesof4 concentrically spaced apertures 13, and from whichl extends axiallyoutwardly the cylindrical andexteriorly threaded base body, in thepresent instance the threads being shown eX- tendingthroughout itslength, although this may not be found essential. The axlekshaft 11 isrepresented as tapered and the huh base secured thereupon by the usualnut 14. These parts constitute the permanent axle assembly of the wheelmounting.. The wheel integrally with an inner spoke flange 16, andsnuglyjfitted around the sleeve'15 there is an outer spoke'iange 17which may be secured to the flange 16 and upon intervening spokes 18 inany suitable manner. lin parallel'spaced relation to the'flange 17,there is a keeper plate 19 mounted fixedly upon.the..ends of bolts 20projected through the wheel body andl having tenfoned ends insertedthrough the plate 19, nuts 21 being engaged upon -the outer ends of thescrews. A stud plate 22 is laterally movable between theflange 17 and,the plate 19, having al series o ffsuitable studs 24 slidable throughthe wheel in registry with the openings 13 when the wheel 1s adjustedsnugly upon thefhub plate. rlhe plate 22 is yieldingly heldin engagingposition by means of leaf springs 25 confined between the plates v22vand 19. The plate 19 receives revolubly'therethrough the outer part ofa wheel releasing member or .cap 26, snugly' revoluble upon theouterJpa-rt of the hub sleeve 15, and provided with a nut head 27 at itsouter part. rlhe cap 26 is formed with three wedge iianges 28therearound, pointing in a/clockwise direction and located at the baseof the flange, the plate 22being formed with an opening sufficientlylarge to receive these flanges therewithim, to lie in the same planewith the plate, and for rotation freely. The plate 22 is formed withlugs 30, tovlie intermediately of the flanges 28 undercut on their sidesadjacent the points of the wedge flanges 28. The cap 26 is held againstloose movement by leaf springs 31 confined between the flanges 28 andthe plate 19.

'hub base.

lt will be seen that by rotating the cap 26 the wedge flanges 28 willlift the bolt plate 22 to disengage thebolts 24 from the hub base flangel2, leaving the wheel free for rotation to unscrew the sleeve from thethreaded body of the hub l0. ln case there is difficulty in unscrewingthe wheel, it may be left resting upon the ground while other wheels ofthe vehicle are chocked, and power applied through the regulartransmission to the shaft l1 in a proper direction, which will initiateunscrewing movement. lt is preferable that the final turns for removalof the wheel shall be effected by hand, the axle being jacked up topermit free turning of' the wheel. ln replacement of the wheel, after itis screwed home upon the hub base, the bolts 24 will be in line with theapertures 13, and the sleeve 26 is then rotated reversely to permit thebolts to slide into place. ln case of undue friction preventing readymovement of the bolts into place, they may be driven in by applicationof pressure to the plate 22.

ln case of a one piece wheel and hub, the sleeve portion l5corresponding to the part 15 before described may be formed integrallywith the wheel body 32, the base portion-of which corresponds to thefiange 16 and lies snugly against the flange l2 of the ln the presentinstance, as showniin Fig. 4 the combined one-piece wheel rim and hubincludes an outer cylindrical rim body 33 from which the wheel disk bodyextends inwardly at an obtuse angle, being curved L gradually outwardagainand recurved into the plane of the base portion 16 of the wheeldisk. At the inner side the rim body 33 is formed with a tire retainingflange 34 of suitable shape, which may be varied to accommodatevarious'forms of tires. At the one side there is provided a removableflange 35, of similar shape in its outer part'. The

body `33 at its outer side is formed with an in-turned crenellatedflange portion 36,

while the removable flange 35 is formed with an inwardly extendingfiange portion '37 adapted to lie snugly against the portion 36 andconceal the same. Upon the inner edge of the flange 37 tongues 38 areformed, extending inwardly a shortdistance parallel d with the axis oflthe wheel andthence being` recurved so as to lie loosely against theinner sides of the crenelles 36, the blank for the rim 35 beingcrenellated on its inner edge to provide the tongues 38 at intervalscorre- -sponding to the spacing of the crenelles 36.

By this construction, the flange 35 being presented against the outeredge of the rim 33 so that the tongues "38 enter between the crenelles36, bv alslight rotary movement the tongues 38 will engage behind thecrenelles to hold the rim 35 against detachment. If desired, a shoulder39 may be formed upon the rim 35 to engage over the inner face of thebody portion at the outer edge so that the flange 35 may be steadi'ed.Yupon the rim portion 33 in its presentation vand adjustment by rotarymovement. At one point in the rim 33 an opening 40 is formed to receivethe valve stem of an inner tube and if v desired, theopening 4() may beprovided -with any usualfitting familiar upon wheel the rim body 33 andflange 35, 'or'nearly so.

rl`he plate 43 may be extended-'at-iits outer part slightly beyond theflange 35 lso that it may be readily struck with a blunt instrument toloosen it if needed. lWhen the tire is to be mounted upon the wheel, thetube is adjusted within the shoein the customary mannery and the shoeand tube presented to the rim, the valve portion first, the latter beinginserted through the opening in the lock plate 43 and opening 40 afterwhich the remainder of the shoe with the enclosed tube is swung inwardlyupon therim and adjusted against the inner flange before mentioned. Thedetachable flange 35 is then presented and engaged in place as beforeindicated, the outer part of the plate 43 being drawn into the recess42. When the tire is inflated, the plate 43 will be forcibly pressed bythe shoe., into the channel and recess in such manner that it cannot bereadily disengaged, and relative rotation of the detachable flange andrim-body will be prevented.

Liability of loosening of the key member .43 may'also be further guardedagainst by the clamping ofthe: valve stem thereagainst by the usual nut44, or its equivalent in case such a device is employed.

In pla'ceof the wedge or inclined elements I v28 of the member 26 it maybe desirable to use a screw thread for drawing the locking bolts, and amethod of such application is shown in Figs. 7 and 8. In the first namedof these two views, the parts 10 to 15 first described are practicallyduplicated, with the exception thatthe member 15a corresponding to theone 15 before mentioned is masses and the spring having an interiorshoulder 54 which rests upon the ring 52. The cap is exteriorly threadedat its base and engaged in an interiorly threaded annular flange 55formed upon the bolt carrying plateA 22. rlhe cap is. of such dimensionthat when the wheel is assembled and engaged upon the hub base element,the base of the cap projects a distance outwardly from the adjacent partof the plate 22 to permit rotary movement of the cap, screwing it intothe flange and thereby drawing the flange outwardly, and with it theplate 22', whereby the bolts will be disengaged. ln order to hold thecap 27 against casual unscrewing and disengagement from the assembly, aretaining screw 55 may be engaged through its outer part and with thehub sleeve 15a.

in F ig. 8 a further application of this method is shown, in which theouter portion of the cap member is' omitted, and the hub sleeve exposedand the cap over the axle nut, instead of the cap before shown., acollar 56 being employed engaged with a bolt-carrying member 22a similarto the one 22', the spring 53a and other parts being similarlyassociated therewith, with the exception that no element correspondingto the ring 52 is required, arid the spring is confined by a flange582iL on the Wheel hub body 64.

At the same time, in the last mentioned view, the method of mounting thewheel upon a non-driving axle or spindle, and also the mounting of theintegral wheel and hub lbody withmy invention, is indicated at .58.

The hub plate member 59 in this instance is iitted to -receive rollerbearing races 60 and 61, and is provided with a short interiorlythreaded part 62 with a, horizontal bearing portion 63 outwardly thereofupon which the hub element 64; of thes'wheel 58A snugly fits forrotation, suitable interior threads being provided at the inner part toengage with the threads 62. The projection 65 at the inner side of theplate `59 may be held with a tool to prevent the hub from rotating whenthe wheel is being mounted.

'The wheel illustrated in Fig. 4 may be formed in different ways, onebeing to form the disk` portion by pressing between two dies which maybe shaped to at the same time extrude the part l5', or this part may beJformed by subsequent operations. The rim body if not formedsimultaneously with the disk portion, may be` formed as a separateelement, and the disk body formed with a slightly greater diameter thanthe interior diameter of the rim, and forced into place within the rimby suitable jacks, either with or without. provision in the engagingsurfacesI for preventing relative rotative movement, and the parts maybe welded if desired, or they may be put together with a loose fit andwelded;
